Disney land, info needed

Hi friends,

We are going on a five days trip to Orlando. Please suggest me what all places to cover in five days, we are traveling with inlaws aged around sixty and my son two yr old. We have planned fr magic kingdom, we might go for sea world or universal studios.

Since my kid and pils won't go for rides, we are thinking to drop universal studios and go for sea world.

Pls suggest what will be better and other place that can be covered.
